Abstract
La présente invention concerne un dispositif de repérage pour produire des effets spéciaux sur une image de télévision. Ce dispositif comprend un mélangeur 17 vers lequel sont dirigées une première image vidéo Angström et une seconde image vidéo B, cette seconde image passant par un circuit de compression 2 Un signal de zone de saturation pour la première image est transmis par un circuit de porte 12, à un circuit de calcul 14 de façon à comprimer l'image B dans un cadre plus grand que le cadre de la zone prédéterminée. Application notamment aux effets utilisés lors des journaux télévisés.
